Show answer & explanation
Correct answer: B
Solution: Use the relation f = 1 / T.
Convert the period to seconds: 10 ms = 10 × 10^-3 s = 0.01 s.
Compute the frequency: f = 1 / 0.01 s = 100 Hz.
Final answer: 100 Hz
Note: Common mistakes come from incorrect unit conversions. For example, 1000 Hz would correspond to a 1 ms period and 10000 Hz to a 0.1 ms period; neither matches the given 10 ms period.
